300MA HIGH PSRR LOW DROPOUT CMOS LINEAR REGULATOR FSP2131 „ z z z z z z z z z z z FEATURES Low dropout voltage: 180mV at 300mA (Vo=3.3V) Quiescent current: Typ. 65µA 2% Voltage Accuracy High PSRR: 70dB at 1KHz Thermal Shutdown Current Limiting Excellent line and load regulation Fast response Short circuit protection Low temperature coefficient Space saving SOT23-3L package „ GENERAL DESCRIPTION The FSP2131 series of positive voltage linear regulators feature low quiescent current (Typ. 65µA) and low dropout voltage, making them ideal for battery powered applications. Their high PSRR make them useful in applications where AC noise on the input power supply must be suppressed. Space saving SOT23-3L package is attractive for portable and handheld applications. They have both thermal shutdown and a current limit feature to prevent device failure from extreme operating conditions. They are stable with an output capacitor of 2.2µF or greater. „ z z z z z z z APPLICATIONS Cordless phones Cellular phones Bluetooth earphones Digital Cameras Portable electronics WLANs MP3 players „ PIN CONFIGURATION (Top View) 1 3 2 „ PIN DESCRIPTION Pin Number 1 2 3 Pin Name VIN VOUT GND Pin Function Input Output Ground www.DataSheet4U.com „ BLOCK DIAGRAM 1/11 2007-4-19 300MA HIGH PSRR LOW DROPOUT CMOS LINEAR REGULATOR FSP2131 „ TYPICAL APPLICATIONS CIRCUITS „ ABSOLUTE MAXIMUM RATINGS Parameter Input Supply Voltage Output Current Output Pin Voltage ESD Rating Internal Power Dissipa...
